FREDA. BRESSMER AND JAMES SHELI-IAMMER, 0F MACON COUNTY, ILLINOIS.

DRAFT-EVENER.

To all whom it may concern:

Be it known that we, FRED A. Bunse- MER and JAMES SHELHAMMER, citizensof the United States, and residents of Macon county and State ofIllinois, have invented new and useful Improvements in Draft- Eveners;and our preferred manner of carrying out the invent-ion is set forth inthe following full, clear, and exact description, terminating withclaims particularly specifying the novelty.

This invention relates to an improvement in draft eveners and moreparticularly to devices of this character which are primarily intendedfor use in connection with plows or other agricultural implements andthe object of the invention is the provision of a simple and efficientdevice of this character which will effectually eliminate all sidedraft.

Other objects of the invention will be apparent from the detaildescription herein when read in connection with the accompanyingdrawings wherein a convenient embodiment of the invention is shown andwherein like numerals of reference refer to similar parts in the severalViews.

In the drawings, the figure is a perspective view of a draft evenerconstructed in accordance with the present invention.

Referring now more particularly to the drawings, 10 designates the outerends of the arms of the beam of a plow Or other agricultural implement.Pivotally secured between the arms 10 by means of suitable bolts is aU-shaped member 10, which normally rests upon a bench 11 which connectsthe arms 10 and underlies the lower edges thereof. The front portion ofthe U- shaped member 10 is provided with notches 13 and 14 in the upperand lower edges thereof.

15 designates a clevis which extends forwardly from the end of the beamand is formed of two superposed metallic plates 15 and 15 the rear endsof which fit within the notches 13 and 1 1 formed in the upper and loweredges of the U-shaped member 10. The plates 15 and 15 of the clevis arerigidly clamped to the U-shaped member 10 by means of clamping bolts 16which pass through said plates and are positioned on opposite sides oftheir connection with said U-shaped member. The plates 15 and 15 of theclevis are provided intermediate the Specification of Letters Patent.

ends thereof with laterally offset portions 17 so as to throw the outerportions thereof at one side of the center of the plow beam. The forwardend of the plate 15 of the clevis is positioned in a plane above theplane of the main portion of said plate, the plate being bent at 18 toaccomplish this result, while the outer end of the plate 15 of theclevis is positioned in a plane below the plane of the main portion ofsaid plate, said plate being bent downwardly at 20 to accomplish thisresult. ltigidly clamped between the plates 15 and 15 of the clevisadjacent the bent portions 18 and 20 thereof by means of a suitableclamping bolt 23, is a plate 22, the forward end of which terminates insubstantially the same plane as the outer ends of the arms 15 and 15 ofthe clevis. Pivotally supported between the plate 22 and the upper plate15 of the clevis is a beam 31, the pivot of said beam being positionedat one side of the center thereof so that the greater portion of thebeam will be positioned on the right hand side of the clevis.

Pivotally supported between the plate 22 and the lower plate 15' of theclevis is a beam 28, the pivot of said beam being at one side of thecenter thereof, and the beam being secured with the greater portion ofits length at the left of the clevis 15. The beams 31 and 28 may bepivotally secured in position in any suitable manner, a single pivotbolt 30 being conveniently employed for this purpose which passesthrough the outer end portions of the upper and lower plates 15 and 15of the clevis and also through the interposed plate 22. A double tree 32is pivotally connected to a clip 33 which is adapted to be secured tothe outer portion of the long arm of the beam 31. Means are preferablyprovided for adjusting the clip 33 longitudinally of the beam 31 and tothis end the beam is provided with a plurality of openings in the outerend there'- of and the clip is secured to the beam by means of afastening bolt 35 which may be passed through any one of said openings.

Pivotally connected to the short end of the beam 31 is a link 38 therear end of which is pivotally connected to one end of a beam 241 whichis positioned between the inner ends of the plates 15 and 15" of theclevis and is pivotally connected thereto by means of a suitable pivotbolt 25. The pivot PatentedOct. 8,1912.

bolt 25 passes through the beam 2 1 at one side of the center thereofand the greater portion of said beam is positioned at the right of theclevis 15. The corresponding ends of the beams 31 and 24 are preferablyprovided with a plurality of openings there in through which the pivotbolts which connect the ends of the link 88 to such beams, pass so thatthe points of connection of the link with the beams can be adjusted. Theouter portion of the beam 24: which is positioned at the right of theclevis 15 is ivotally connected to one end of a link 47, the other endof which is pivotally connected to the portion of the beam 28 which ispositioned at the right of the clevis 15. The ends of the beams 2a and28 which are connected by the link 47 are provided with a plurality ofopenings therein through which the pivot bolts of the links pass, sothat such bolts can be secured in any of such holes to vary the pointsof connection of the link with said beams.

Pivotally connected to the portion of the 'beam 28 at the left of theclevis 15 is one arm of a Z-shaped clevis 42 the upper arm of saidclevis projecting forwardly beyond the beam 31, heretofore referred toand having pivotally connected thereto a double tree 45. The lower armof the clevis 12 is preferably adjustably connected to the beam 28, suchbeam being conveniently provided with a plurality of openings therein,in any one of which the pivot bolt of the clevis may be secured.

It is believed that the operation of the device will be obvious from theabove description.

l/Vhile a convenient embodiment of the invention is illustrated in theaccompanying drawings, it will be understood that many changes may bemade to the form and construct-ion therein shown without departing fromthe spirit and scope of the invention as defined in the appended claims.
